or: why do these crazy letterboxers
have letters and numbers after their signatures?

P = boxes placed

F = boxes you've found

X = stamps you've exchanged with other letterboxers you've found on the trails or at gatherings.

Right now, I'm a P15F36X6 (P16, if you count the virtual one). But I'm working on getting all those numbers into double-digits. If I do end up hiking that unholy trail later this year, I'll have the Ps up there in the zillions, I'm sure. :)
